How do change 13 1/4 into decimal form
Bess [88]
That would be 13.25, 13+1/4
                                = 13+(1 divided by 4 which is 0.25)
                                = 13+0.25
                                Which is 13.25 so your answer is 13.25, good luck hope that helps :D

Question 5 (1 point)
riadik2000 [5.3K]

Answer:

The area of sector AOB is 75.36 unit²

Step-by-step explanation:

Consider the provided information.

Circle O with minor arc AB=60 degrees and OA =12.

We need to find the area of sector.

Area of the sector: A=\frac{\theta }{360} \times \pi r^2

Substitute \theta=60 and r =12 in above formula.

A=\frac{60}{360} \times 3.14\times (12)^2

=\frac{1}{6} \times 3.14\times 144

=24\times 3.14

=75.36

Hence, the area of sector AOB is 75.36 unit²

irinina [24]
The diameter is 24 since if you ÷ it by 2 you get 12 to get area it is radius squared so 12 × 12= 144×pi which is 3.14= 452.16 mm you can even check in a calculator

In the equation, 7 (3a+12)=168 , what are some of the steps that should be taken to solve for x? Select all that apply.
Svetradugi [14.3K]

7(3a + 12) = 168 ← ( divide both sides by 7 )

3a + 12 = 24 ← ( subtract 12 from both sides )

3a = 12 ← ( divide both sides by 3 )

a = 4

OR

distribute the parenthesis by 7

21a + 84 = 168 ← ( subtract 84 from both sides )

21a = 84 ← ( divide both sides by 21 )

a = 4
